What did you do with your Z today

Just got done changing my Diff fluid. This was the first time its been changed since I installed my OS Giken LSD about 6K miles ago. Boy it was nasty. Black as tar and as thick also. Smelled burnt to me but not sure if that's normal with this oil being it has 6K miles and three track days. Recommended intervals per OSG is 15K under normal circumstances. So with my track days and hard driving it was time. Good thing was the drain plug didnt have much of any metal shaving on it so I'm happy there.

OSG fluid is 80w 250 and I highly suggest only using there oil. My LSD has alway been quit. The only time I've heard it pop or bind is after a very long day at the track and after a few hours of cooling down it never made a peep afterwards.

I just hit 30k and I am planning a full fluid flush come spring when I put it back on the road. Im totally scared of what my dif fluid is gonna look like considering its never been changed yet.

Im gonna have to look into the OSG 80w 250 as per your recommendation.

I'm sorry I might of mislead you. But don't use OSG fluid with any other LSD. It's only specifically for OSG LSD. There some guys that run Motul oil in there OSG's. Which there's no harm by that. But it will make the OSG LSD bind a little more. I've seen this first hand. Motul is good oil and far cheaper. But I'd rather pay $90 to change my diff being it only needs to be changed ever two oil changes if your hard on your car as I am.
